SHEET-METAL BED-RISER.

SPECIFICATION forming part of Letters Patent No. 758,917, dated May 3,1904.

Application filed October 21, 1903.

To all whmn it may concern:

Be it known that we, J AMES MONROE HOL- LAND and FRANKLIN HOLLAND,citizens of the United States, residing at Baltimore, State ofhlaryland, have invented certain new and useful Improvements inSheet-Metal Bed-Risers, of which the following is a specification.

This invention relates to a bed-riser for the corners of woven-wiremattresses or other stretched-fabric beds. Four of these bed-risers areusually employed in eachbed, and each riser sets upon a tube, two ofwhich constitute the longitudinal or side stretcher-bars of thewoven-wireanattress frame. A cross-bar, of angle-iron, comprises the endpieces of this mattress-frame, and such bar rests upon two of thesebed-risers and is secured thereto. Each bed-riser of this type isprovided with a laterally-projecting prong, which when themattress-frame is in position upon the bedstead rests on the side bar ofthe bedstead, and thereby supports the mattress-frame. Heretofore thisstyle of bed-riser has been made of cast metal, and it is found thatowing to the brittleness of cast-iron the projecting prongs aresometimes broken off in the shipment of the goods, and when one of theserisers is thus broken the entire woven-wire mattress and its frame isrendered practically worthless, because a new riser can be substitutedonly at the factory where the special machines are employed forstretching these wire mattresses. The desideratum, therefore, is abed-riser of this type made of wrought iron or steel cut or stamped bydies from sheet metal.

Our invention consists of the novel construction of a sheet-metalbed-riser, as hereinafter described.

Referringto the drawings, Figure 1 is a perspective view of the improvedbed-riser. Fig. 2 is a side elevation. Fig. 3 is a View, on a smallerscale, of a sheet-metal blank from which the bed-riser is made. Fig. 4is a side view in elevation, showing the bed-riser in section and in itsposition between the longitudinal tube and the end bar. Fig. 5 is a topplan view showing the parts in their position as when the mattress is ona bedstead. The

Serial No. 177,891. (No model.)

parts shown comprise one corner of a mattress-frame and bedstead. Fig. 6is a perspective View of the bed-riser, showing an additional feature.Fig. 7 is a view of a blank from which the riser shown in Fig. 7 ismade. Fig. 8 is a vertical section through the riser, showing the disk.Fig. 9 is a side elevation of this form. In this instance thesaddleflange is shown. Fig. 10 is a side elevation showing this form ofbed-riser in section and connected with the side tube and the angle-bar.

The form of device shown in Figs. I to 5, inclusive, will first bedescribed. The letter A designates one of the side bars or stretchers ofan ordinary wOven-wire-mattress frame. This bar is an iron tube. Theletter B designates the angle-iron cross-bar. of which two are used inthese frames, one at the head end and the other at the foot end. Theriser C (shown in perspective in Fig. 1) is seated on the said tube Aand supports the said angleiron cross-barB in an elevated position abovethe tube. The prong (Z of the riser projects laterally at one side andrests upon the side rail F of the bedstead, as in Fig. I, and therebysupports one corner of the mattress-frame. The letter F denotes thecorner-post of the bedstead. The improvement consists in first formingor cutting out the blank of sheet metal shown in Fig. 3. The two ends ofthis blank have similar ogee curves r, and the two edges g are parallel;but one end is shorter than the other and has an offsetting flange it,which extends about or nearly one-fourth of the length of the blank. Theblank shown is then bent to form a square or four-sided pedestal orriser C, and the offsetting flange it now has position at one of thesesides and makes this side higher than the other three sides. The twoends having the ogee curves are brought flat together in close contactand secured together by rivets and constitute the prong (I, whichprojects laterally from one side of the pedestal or riser (I. It is notto be understood that the prong of two thicknesses of sheet metal mustproject from the middle of one of the four sides, as we contemplatevariations from this form. The ogee curve constitutes the top edge ofthe prong,

and the bottom edge is straight. Two saddle-flanges j are formed at thebase of the riser to fit on the rounded surface of the side tube A, andthereby afford a stable bearing or seat. These saddle or curved flangesj j are formed by forcing the sheet metal at the lower edge of twoopposite sides of the square riser to take a lateral or right-angledposition, as plainly shown in Figs. 4 and 5. The angle-iron cross-bar Bsets upon the riser O, as shown in Fig. 4 and as indicated by brokenlines in Fig. 5. This cross-bar in practice extends entirely across themattress-frame at right angles to the two side tubes A, each end of thebar being seated on a riser. A bolt 74 passes through one side of theangle-bar B, down through the square riser, and transversely through thesaid tube A and is secured by a nut in on the under side of the tube, asseen in Fig. 4:. It will now be seen that the construction of the bentsheet-metal riser C, with two curved or saddle-shaped flanges jj at thelower edge, enables the riser to be clamped very tightly to the sidetube A without any injury to said tube or without liability of crushingit or indenting it, as often is the case with other devices. The wovenwire Z is secured in the usual way to the upright flange of theangle-bar B by a plate m and bolt n, and it will be seen the flange h atthe top and one side of the riser prevents the angle-bar B from movementwhen drawn by the stretched woven wire.

The form shown in Figs. 6 to 10, inclusive, will now be described. Thisform of bed-riser has all the essential features of construction of andis formed into shape in the same manner as the riser shown in the firstfive figures of the accompanying drawings and in addition to thatdesired construction has a feature which serves to close the end of theside-bar tube to exclude dirt and make it more sightly and also byfilling the end of the tube effectually prevents theend from beingmashed or partly flattened. The added feature referred to consists ofmaking one wall 39 of the angular pedestal or riser longer verticallythan the others, and this increased length of one wall projectsdownward, as at p, below the other walls, and when the riser is inposition on the side tube of the mattress-frame this downprojecting part1? serves as a cap that closes the end of the side tube. This cap partof the riser is provided on its inner face with a disk g, which issecured, preferably, by a rivet q. The diskis of proper size to enterand snugly fit into the open end of the side tube A. The opposite wall1" of the riser at its lower edge has a curved saddle-notch or openingthat is adapted to fit on the rounded surface of the side tube A. Thelateral flange may be provided at this saddle-notch, as in Fig. 9, or itmay be omitted, as in Fig. 10.

Bed-risers thus made of wrought sheet metal with a prong (Z of twothicknesses of metal will not be broken off during shipment or at othertimes and are therefore more durable and serviceable.

Having thus fully described our invention, what we claim as new, anddesire to secure by Letters Patent, is

1. A wrought-sheet-metal bed-riser bent in the form of angular sides andhaving a-prong.

formed by two thicknesses of metal in close contact and securedtogether, said prong projecting laterally from the riser.

2. A wrought-sheet-metal bed-riser bent in the form of angular sides andhaving at one or more of said sides a curved or saddle-shaped flange atthe lower edge and provided with a prong formed by two thicknesses ofmetal in close contact and secured together, said prong projectinglaterally from the riser.

3. A wrought-sheet-metal bed-riser bent in the form of angular sides andhaving a prong formed by two thicknesses of metal in close contact andsecured together, said prong projecting laterally from the riser and thewall of one side of the riser projecting downward below the other sidesto serve as a cap for closing the end of a tube.

4. The combination of a side tube of a mattress-frame; a sheet-metalbed-riser bent in the form of angular sides and having a prongprojecting laterally from the riser and the wall of one side of theriser projecting downward below the other sides and closing the end ofthe said side tube and provided with a disk-shaped portion fittingsnugly into the end of said tube.

In testimony whereof we aflix our signatures in the presence of twowitnesses.
